Labor state secretary John Dowling was cagey about whether more robocalls would be used in the lead-up to the election.

"From Labor's perspective, to have someone like Norm with that respect and credibility supportive of the decisions we made (about ending power sharing), we want to share that."

Deputy Liberal Leader Jeremy Rockliff said Labor was "up to the same old dirty tricks and dishonesty that they used in the lead-up to the 2010 election".

"Back then, Labor unleashed a wave of robocalls saying that the Greens wanted to legalise heroin.

"Yet just weeks after they made the claim, they did a deal with the Greens to get back into government.

"This time they are trying to con people into believing that they won't do another deal with the Greens.

"Tasmanians won't be fooled."

Mr Britton said he was comfortable Labor had divorced itself from the Greens.

"I believe it's arrogant to disregard the will of the people."

"I note that (Premier) Lara Giddings has said there will be no formal agreement with the Greens and there will certainly be no Green ministers in a hung parliament if she forms a government under those circumstances."

He said the government had performed "pretty well".

"Our local bloke, (Deputy Premier) Bryan Green, he's burrowed in, with the Greens being negative about mining and aquaculture and uneasy with agriculture and opposed to any type of forestry development.

"I think he's done well."

The Liberals and Greens have ruled out using robocalls in the campaign.

Greens Leader Nick McKim described them as "intrusive and impolite technology".
